Given numbers are 542,155,940,668
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 542,155,940,668 is 1318788980.
Find LCM of 542,155,940,668 with Prime Factorization
| 2 | 542, 155, 940, 668 |
| 2 | 271, 155, 470, 334 |
| 5 | 271, 155, 235, 167 |
| 271, 31, 47, 167 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 271 x 31 x 47 x 167 = 1318788980
Therefore, the lowest common multiple of 542,155,940,668 is 1318788980.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
542 x 155 x 940 x 668 = 52751559200
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
542 : 1, 2, 271, 542
155 : 1, 5, 31, 155
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
668 : 1, 2, 4, 167, 334, 668
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 542,155,940,668, is 1.
Now, the common factors can be found like this.
542:2x 271
155:5x 31
940:2x 2x 5x 47
668:2x 2x 167
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 5 = 40
Therefore, the value for common factors is 40.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 52751559200/(1x40)
LCM = 52751559200/40
LCM = 1318788980
Thus, we can understand that the LCM of 542,155,940,668 is 1318788980.
